Classify each reactant and product in this reaction as an acid or base according to the Brønsted theory. HF + H2O = F + H30+

Answer Bank
HF
H30+
F-
H2O

Reaction: .

Explanation:

In the Bronsted-Lowry acid-base theory, the acid in a reaction is the species that loses a proton, . The resultant species would be the conjugate base of that acid.

On the other hand, the Bronsted-Lowry base in a reaction is the species that accepts a proton . The resultant species would be the conjugate acid of that base.

Identify the conjugate acid-base pairs in this reaction. Note that the two species in each pair are related by the gain or loss of a single proton. Therefore, their formula should look similar to each other.

For this reaction, and , as well as and form two similar-looking reactant-product pairs:

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
